A metamorphic inorganic framework that can be switched between eight single-crystalline states

A metamorphic inorganic framework that can be switched between eight single-crystalline states

The design of highly flexible framework materials requires organic linkers, whereas inorganic materials are more robust but inflexible. Here, by using linkable inorganic rings made up of tungsten oxide (P8W48O184) building blocks, we synthesized an inorganic single crystal material that can undergo at least eight different crystal-to-crystal transformations, with gigantic crystal volume contrac...

Can Spurious States Be Useful?

Michel e C eccarelli Isti t uto di Ri cerca sui Sist emi In form atici Perelleli, IR SIP-CNR 80125 Nap oli, It aly Ab stract. Additive automata are analyzed and used as associative memories. Th eir storage capacity is comput ed as well as the attrac tion basin of each memorized pattern. We show how such systems can be used when the patterns to be memorized have a subset of relevant features; "s...

Can Metastable States be Trapped?

Synchronizers (commonly implemented as chains of two flipflops) are used to reduce the probability that metastable states, emanating from asynchronous input transitions, propagate to state/data flip-flops and cause unwieldy catastrophes. Another way to think of this is that synchronizers “trap” metastability, preventing it from being observed by others circuits until a failure rate criteria is ...

Staphylococcus lugdunensis; a pathogen that should be considered in Iran

Background: Staphylococcus lugdunensis is Gram-positive cocci of the staphylococcaceae family. S. lugdunensis despite having a clotting factor (wall coagulase), was classified in the coagulase negative staphylococcus group (CoNS) for lack of free coagulase. Although this bacterium is part of the human normal flora, in terms of virulence, S. lugdunensis is in second place after S. aureus. S. lug...
